When is the best time to take L-glutamine?

The best time is immediately after training when muscles need recovery most. Alternatively, you can split glutamine into several doses throughout the day — morning, post-workout, and before bed. This ensures steady amino acid levels and supports continuous recovery throughout the day.

How much L-glutamine should I take per day?

Athletes are recommended 5-10 grams per day. For lighter training loads, 5 grams is sufficient, while more intense training may warrant 10-15 grams. Glutamine is safe even in larger amounts, as the body continuously uses it for energy and immune processes.

Does L-glutamine support the immune system?

Yes, glutamine is the primary energy source for immune cells. Intense training lowers blood glutamine levels, which can make athletes more susceptible to infections. Studies show that glutamine supplementation reduces the incidence of upper respiratory tract infections in marathon runners and other endurance athletes.

Can L-glutamine be combined with other supplements?

Yes, glutamine pairs well with most supplements. Popular combinations include glutamine + BCAAs for recovery, glutamine + creatine for muscle mass, and glutamine + probiotics for gut health support. Glutamine can be mixed directly into your protein shake.
